Porocarcinoma of the Eyelid Presenting as an Umbilicated Lesion
Porocarcinomas are unusual cutaneous tumors developing from eccrine sweat glands. Rarely occurring on the eyelid, the 6 previously reported cases all displayed larger lesions than the current case without distinguishing characteristics. None recurred, compared with lesions elsewhere on the integument showing 20% local recurrence, 20% lymph node involvement, and 10% metastasis to solid organs. The better prognosis for eyelid lesions may reflect earlier detection and smaller size.© 2021 The American Society of Ophthalmic Plastic and Reconstructive Surgery, Inc.
